Dust Hazard Analysis (DHA)

Dust Hazard Analysis Helps Your Facility and Personnel Stay Safe

Companies that are aware of the risks of combustible dust and facility hazards are more likely to prevent or manage an incident before it occurs. Combustible dust fires and explosions can be catastrophic and can lead to crippling property damage, loss of life and business interruption. A Dust Hazard Analysis (DHA) is designed to protect your facility against combustible dust hazards.

Combustible dusts are finely divided solids that present flash fire and combustion hazards under certain conditions. These dusts can be found in most industries and come in many forms including (but not limited to): flours, grains, hops, sugars, charcoal, lactose, aluminum, rubber, wood and paper dust, etc.

A typical DHA includes:

• A systematic review to identify and evaluate the potential fire, flash fire, and explosion hazards associated with the presence of one or more combustible particulate solids in a process or facility.
• Identification hazards for each process, facility, and components, as well as pinpointing safe operating ranges and proper safeguards.
• Data collection for system and performance requirements.
• Advice for combustible particulate solids management, process hazard analysis, and documentation of all results in the DHA.

White Paper: Protect Against Combustible Dust Explosions & Fires

Fire and explosion risks are present in most industries that manufacture, handle, or generate combustible particulate solids and there are many materials that can be explosive in dust form. Industries such as food and grain, mining, and plastics manufacturing can be particularly vulnerable to combustible dust incidents. Where these hazards are present, a DHA may be required to identify, assess and mitigate the dangers of fires, deflagration, and explosions from combustible particulate solids.

Under the NFPA 652 “Standard on the Fundamentals of Combustible Dust”, a DHA will be required for industrial manufacturers with existing processes and facility components. ATEX Directives 99/92/EC and Directive 94/9/EC also require dust hazards to be evaluated at facilities throughout Europe.
